By fitting a fin cooling package to the VK evaporative cooler, a dry cooling element is combined with wet cooling and thus achieves a higher dry cooling performance compared with the classical evaporative cooler.
This model of the VK with hybrid design is used when the cooling load is to be discharged air-cooled at cool ambient temperatures without having to forego the low recooling temperature at high ambient air temperatures.
Requirements
- greater demands on the quality of the cooling water
- water-sided maintenance/cleaning is limited to cooling tower part
- antifreeze, brine or temperature over 70 C present in the cooling water
- cooling water system with high pressure
Areas of use
- in the open
- on top floors
- in high rooms
Your benefit
- no vapour plumes
- higher switching levels for wet/dry operation
- no sedimentation in the cooling water circuit
- no corrosion in the cooling water circut
- compact design
- no enclosed room necessary
- cleaning of cooling water only necessary at considerably extended operating periods
- low water treatment costs
- if necessary, the secondary circuit can be switched off during the cooler periods of the year (operation by air cooling only)
